Hey! Listen!

Hey_listen is an event-dispatcher for Closures, Structs, Enums and other types. On another note, hey_listen supports prioritised/ordered dispatching and aims to add parallel dispatching as well!

Everyone is welcome to contribute, check out the CONTRIBUTING.md for further guidance.

Example

Here is a quick example on how to use the event-dispatcher:

extern crate hey_listen;
extern crate parking_lot;

use hey_listen::Listener;
use hey_listen::EventDispatcher;
use std::sync::Arc;
use parking_lot::Mutex;

#[derive(Clone, Eq, Hash, PartialEq)]
enum EventEnum {
    EventVariant,
}

struct ListenerStruct {}

impl Listener<EventEnum> for ListenerStruct {
    fn on_event(&mut self, event: &EventEnum) {
        println!("I'm listening! :)");
    }
}

fn main() {
    let listener = Arc::new(Mutex::new(ListenerStruct {}));
    let mut dispatcher: EventDispatcher<EventEnum> = EventDispatcher::new();

    dispatcher.add_listener(EventEnum::EventVariant, &listener);
}

Installation

Add this to your Cargo.toml:

[dependencies]

hey_listen = "0.1.2"

parking_lot = "^0.5"

and this to your crate's root:

extern crate hey_listen;
extern crate parking_lot;
